Deadly Kennen

Released in 2010 as one of the first alternate skins for the Heart of the Tempest, Deadly Kennen sat in the Silver Age line and cost 520 RP. That makes it one of the oldest cosmetics still tracked for this champion.

Today it is listed as Legacy. Riot removed it from the standard store rotation and placed it in the Legacy vault, so it returns for purchase only during one of the periodic legacy sales or events.
